WORK-SUPPORTING STAND.

v Application filed May 1,

which is light and, therefore, readily shifted to any desired point of the machine shop, which is firm, and which may be disassembled for packing and shipment and may be readily assembled whenever desired.

A further object is to provide a motor stand of this character which will support the motorblock, crank case and allied parts at the right height for overhauling and working thereon, and which is so constructed v as to permit the-motor block to be swung to aplurality of positions so as to make every part of the motor block readily accessible for operation. a

A still further object is to provide in a device of this kind means for keeping the valves from dropping out when the motor block is swung to carry the cylinders into different angles, this means being so con structed as to enable the operator to turn the crank shaft and cam shaft Without bending or buckling the valve stems. 7

Still a further object is to provide a construction of this character by which an entire motor can be assembled comp crank case, transmission cover, etc. p p

7 Other objects will appear in the course of the following description. j v My invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of a work supporting stand constructed in accordance with my invention; p y I Figure 2 is a side elevation of the upper portion of the stand, showing two positions in which the motor may be adjusted; I

Figure 3 is a sectional View through the bar 28, showing the means for engaging the engine block; A

Figure 4sisa sectional View through the bar 28, showing the manner in which the pin 31 is mounted-therein; v f 1 1 Figure 5 is a fragmentary sectional view through the engine block and the supporting a bar 15 showing the manner in which gine block isconnected thereto. 1

Referring to these drawings, it will be seen that my stand comprises the horizontalthe .en-

letely with 1923. Serial No. 635,920.

1y extending angle irons lOwhich form the base of thedevice and to which are attached by bolts, rivets or other suitable means the 'upwar'dlv extending standards 11, these standards being of relatively heavy'iron or other like material. The standards extend upward and slightly inward, and disposed between the parallel portions of the standards is a block 12 of wood or material, this block being grooved upon its. upper and lower faces, and passing through these grooves are the bolts 13 and 14 holding theblock firmly in place, the block preventing any collapsing'of the standards.

Mounted upon the upper ends of the other suitable standards for oscillation thereon is a transverse bar 15 having angularly. bent ends 16 which extend down on the outside faces of the standards, Through this bar passes a bolt 17 carrying anut 18 having a handle 19,and disposed between the standards and surrounding this bolt is a sleeve 20 which prevents the standards from being forced or benttoward each other when the nut 18 is tightened up. The transverse bar 15 constitutes the support for the engine block and for various other parts, of the apparatus which may be attached thereto, and to'this end the transverse bar 15 is formed with a plurality of perforations 21 spaced at any desired distance from 7 each 'other.

For the purpose'fof' holding the supporting bar 15 in any desired position, I form the supporting barwith an opening 22 and attach to one of the-standards a pin 23 which is adapted to extend through the opening 22 and through one of a series of perforations 24 in the standard, this pin being connected to the standard by means of a spring 25. The standard has not only one opening 24 buta plurality'of these openings so that the supporting bar 15 may be shifted into a plurality of positions. Thus it may be turned so that its upper face lies entirely in a horizontal plane or it may be shifted so that itsouter face lies entirely in a ver tical plane or to one or more intermediate positions, and under these circumstances the pin 23 will hold thesupportingbar set or locked in this adjusted-position. I a

The engine block A is adapted to belconnected to the supporting bar15 bytheiusual manifold studs a which are, inserted through 'theapertures 21 in the supporting bar .15.

Over these studs wand against thee'xteri'or inward movement of the pins.

of the bar are placed the sleeves E26, and

engaging the outer ends of the studs 64 are the nuts 27 which bear against the ends of 1 formed integral with the bar 28 and extend ing and then downward in an approximate seini circle from the bar 28 and being pivotedito the nwardly turned ends of thebar 13'by means'of the rivets 30. This cross bar 28 has a plura-lity'of apertures in it, and operating through these apertures are the headed pins 31. These pins at their inner ends are provided with transverse apertures for the passage of cotter pins 32, and surrounding each pin and bearing at one end against the head thereof and at its opposite end cross bar is a coiled spring 33 the headed pins outward until stopped by the cotter pins 32. Thus these headed pins are normally projected and the springs resiliently resist the These pins are disposed in alignment with the valve stems and bear against the valve. Riveted or otherwise attached to the cross bar 28 is a U-shaped clip 3 1, and having screw-threaded engagement through this'clip is a cap screw 35. This cap screw screw into the middle hole I) in the engine block A where the cylinder head cap goes.

It will be seen that this cross bar 28 constitutes a valve holding device which may be turned upon its pivots 30 to bring the pins 31 into engagement with the valves and against the which acts to force that when this device is brought down on the valves thescrew 35 passes into andengages the opening I), as heretofore described. The downwardly turned ends of the 11.5- shaped clip 84-. bear against the face of the engine block and hold the cross bar 28 in such position that the pins 31 will hear propthe valves and thus keep the falling out when the motor to different positions. When erly against valves from block is swung these pins are engine can, be cranked and the stems of the valves will not be buckled, as the springs 30 will compress to permit the movement of the valves.

In order to provide means whereby the transmission, fly wheel, and magneto assembly can be supported on the lower portion of the; stand, I provide the hook-like menibers 54 which at theirupper ends are formed with eyes through which'the bolt l l'p'asse's is adapted to engaged with the valves, the

nee les and which at their lower ends are angularly bent, as at 55, so that, as illustrated n Fig ure 1, the transmission mechanism, fly wheel and the magneto assembly may be supported by these hookshaped members, thus adding weight to the bench or stand when heavy wrench pressure is used for tightening bee.- ings. This motor stand will not twist or slide on a cement floor, as it is provided with small nubs at its four corners which rest upon the floor. At the same time the motor stand is sufiiciently light so that it may readily shifted to any desired'part' of the assembly room or garage. It will be seen that all of the parts can be readily 111mm factured and pressed cold and that they may be readily assembled. This stand, while it is particularly intended for use with Ford and Fordson motors, may be made to hold'any engine block that has a manifold held by studsor bolts. I r
